' BOTTLE CAR,

This invention relates to bottle caps V such as employed to seal milkbottles and which usually comprise a" simple cardboard dlskv adapted to be pressed within the rim of the 6 mouth of the bottle into contact with an anj nular seal. The removal of these caps, without using a special tool,'is troublesome and numerous caps have been brought out in eluding a tongue or tab, usually integral with thefcap, which may be bent up to serve as afinger grip whereby the cap may be removed andreplaced with ease and as often as may be necessary. The ditficulty in provin Fig. 14; and

viding caps'jwith suchtongues is that, to

meet therequ irements of the. cappingma? chines,.thesurfaces of the cap must be sub-' stantiallyfiush and it has sofar been necessary to deform the cap; in some way in the process of manufacture to give access for a finger nail to the end of the tab and with surfacesof the cap.

out causing material projections above the g It is undesirable to deform-the cap in the process ofmanufacture'as it causes extra expense andtroublein manufacture and any departure from a fiat flush surf-ace either at the upper or-undersidemay give] trouble in the capping machinesgor providelrecesses in which dust or .liquidmay collect.

'.My-object, therefore,ris to devisea cap,

provided withhaatab, which presents substantiallyunbroken surfacesbut in'which a simple operation, whenthe cap is to be removed, 'ives access tothe end of the tab.

I attain my object by defining in the cap apart to form a taband a part adapted to be depressed by the finger or a tool to give access to the end-of the tab which is adapted to be-bentup to forma finger grip integrallyattached at its baseto the cap.

The invention is hereinafter more specificaillydescribed and is'illustrated in the accompanying drawings in which 7 7 Fig. 1 is a-plan view ofa bottle cap constructed in accordance with my invention; v Fig. 2'a similar view showing a modification of the same; 1 v

In, the drawings like numeralsof referon the line 17- -17 section on the line 11-11in' the line 16-16,

a section on the line 10-'-10 in en'ce indicate corresponding parts in the 7 different figures v p fReferring particularly to Figs, 1 and 2, 1 is a cardboard disk of ordinary materialand standard size. In it are formed three cuts 2, 3 and 4: in the former" a letter H.

These cuts extend entirely through the card so as to form two tongues 5 and 6. The

cuts are formed with a die having thin outtlng. edges so that the cuts tend to close after v their formation, the sealing of the cuts being completed when the cap is waxed. It is, however, possible by the use of the finger or tool to' depress one tongue, for instance,

the tongue 6, andto thus gain access to the end of. the tongue 5', which may thenbe raised to form a tab integrally connected at its base with the cap. V

It is preferable, however, not to complete? lysever the sides and ends of the tongues.

from the cap, while it is still possible to readily depress one tongue and pull up; the other. A construction forthis purposeis illustrated in Figs. 2, 8, 9 and 10. The

tongue 5'lS outlined by the lines88, which i extend part way' through the cap from one side and the lines 99 whichextend part way through-the cap from the other side. The tongue 5 is similarly outlined by similarycuts in reverse relationship. The cuts on'one' side of the cap are'in offset relationship to the cuts at theother side. The 1'8? sult is that when the tongue 6 is depressed the material of the cap splits in the'central plane betweenthe cuts at the side and end ofthe tongue so that the sides and ends of the tongue are detached and pushed downwards. This exposes the end of the tab 5, which then easily raised. the material oi? the cap splitting in a similar manner.

It will be noted that the ends of the tongues are connected with one another by smaller uncut portions at the corners, but these readily break 1 "ay when the tongues are depressed and elevated as described.

From the construction described it will be seenthat .l have provided in the cap two areas of its surface partly outlined by lines oi? weakness which form tongues one of which more readily depressed than lifted and the other more readily lifted than depressed. whereby one may be broken down to ire access to the end of the other which D 7 may then be lifted to form a tab.

In Figs. '1, Ill and 12, I show a modifier. tion in which the lines 10 outline the tongue '6 and extend nearlybut not quite through the cap, while the lines 11 outlining the sides of the tongue 5 extend nearly but not quite through the cap from the other side. The tongue (5 is readily depressed, the tongue tearing away from the material of the cap at the under side. The tongue 5 may be lifted, the sides tearing away from the upper side of the cap. It is not possible, however, with this construction to make clean breaks, and to assist the material to break cleanly I may form score marks 12 at the opposite sides of the cap as indicated in Fig. 13, these score marks being made by pressure and not by cutting.

In every case there has been formed areas in the cap, one of which is more readily depressed than raised and the other more readily raised than depressed.

In Figs. 1, 52-, 3 and 4 the tongues are shown diametrically opposed with their ends in juxtaposition. Tn Fig. 5 I show a. modification of the tongue 5. In this case the ends otthe tongue are both connected with the disk. but the tongue may nevertheless be readily sprung downwardly sufiicient to give access to the end of the tongue 5.

In Fig. 5 I show a modification in which the tongue (5 extends in a direction at right angles to the tongue 5.

In Fig. 6 I show a. modification in which the tongue 6 extends in a direction at right angles to the tongue Its mode of operation will, however. be substantially the same.

In Figs. 14L to 17 I show a preferred form. The tongue 5 outlined by the Ushaped cut 13 at one side of the cap and the cut 14. at the other. the cuts being offset from one another and each extending part way through the cap. The tongue 6 is formed by a plurality of cuts 15 extending from the bottom of the U-shaped cut 14: parallel to its sides. These cuts preferably extend only part way through the cap. The tongue 6 being thus divided the center thereof is easily pressed down from the uncut side of the tab pulled up to form a finger "rip, said cap having a part adjacent the ot ier end of the tab partly separated from the cap butconnected therewith along a line remote from the base of the tab andadapted to be readily of the depressed to give access to the end tab remote from the base.
